i have been doing SW since dx in may and lost 2 stone, i would advice to test before eating to find out what you can eat.
i like the green days but have to watch the carbs a little,
for instance, chips done in the actifry, with beans and 2 eggs, can raise my BS a little too hight for me..but if i just have a spoon of beans , i'm ok,
i have 2 weetabix or all bran for breakfast, for lunch.. salad, with chicken or with a baked sweet potatoe depending if i'm doing green or red days,
snacks are mullerlight yogurts, a little fruit, SW hi fi bars are great!! as no effect on my bs, and they are filling and sweet
